Bugcode_usb_driver

Ok, recently my wireless internet keeps disconnecting, and I use a USB drive to connect to the internet to the router. After it had disconnected, I am unable to do anything to get it working again, and it seems as if all the USB drives have stopped working. I restart the computer, but just as it's about th start up again, I get the Blue Screen with the error:
BUGCODE_USB_DRIVER.

It made a minidump each time, both of which I have uploaded. If you could take a look at them I would be grateful. I'm not sure if it is anything to do with the RAM. Thank you.
